This is by far the WORST booklet I've ever had to use. The colors of the parts are SO confusing. It's hard to tell blue from green, blue from purple. We guessed at a lot of parts and used extras that we have to complete it. That's my only complaint
No, I would not recommend this to a friend.

Cool set
on November 21, 2025
Posted by: jennajburn_2625
[This review was collected as part of a promotion.] I would call myself a LEGO novice (this is my 3rd set) but the overall build was easy. The instructions were clear to follow, and I completed the set in 2 hours, and there were no missing pieces.
As a gemologist, I was excited about the idea of having the rough gemstone Legos to display in my office. While they don’t really look like the real thing, they still make a cool decoration. The overall set is slightly smaller than I was expecting but still looks nice.

I was really excited when I first saw this set, especially since I’m a huge fan of minerals and stones. Unfortunately, after putting it together, I was left feeling pretty let down. The finished build doesn’t resemble the stones or minerals in any recognizable way—it just misses the mark entirely.
I was hoping for something that would really reflect the unique and mesmerizing beauty of minerals, but unfortunately, this set didn’t hit the mark.
No, I would not recommend this to a friend.

Beautiful display piece

[This review was collected as part of a promotion.] This is a great set! My 8 year old loves Lego and also collects gemstones so it was perfect for him to build. It’s a beautiful display piece. The biggest complaint was that one of the instruction booklets was misprinted and was missing some pages while other pages were out of order. But we just used the instructions online and everything came together.

Really fun!

This was my first Lego build (as an adult) and I found it to be really fun! I was sad when it was over. It wasn’t overly complicated so I think it was just right for a first timer. It is also really pretty to display and catches the light really nicely.
I would recommend this to a friend!

This was a super fun set to build, and I love that you can arrange them in many different ways. It looks really nice on display as well. The options are endless, you can keep them together, separate them, rearrange them, etc. Really great build.
I would recommend this to a friend!

Beautiful Set Needs Improvement

Verified Purchase:No
This is a beautiful set with some interesting bricks to make up crystal structures. That being said, I found it difficult to distinguish between colors at times and there were missing pieces so I had to improvise. As an avid rock and crystal collector I was so excited to receive this as a gift and it looks great amongst my real collection!
I would recommend this to a friend!

Fun art to build
on November 24, 2025
Posted by: hizeelt_7133
[This review was collected as part of a promotion.] Very cute set that’s super fun to put together. There’s a ton of tiny pieces that were tedious to put together but the end result was beautiful. It wasn’t too difficult to put together but it did take me close to 3 hours. Sets were packaged well with a few extras just in case and the directions were clear on how to put together!
